#- Watch out for sizing errors when not divisible by 2 #- Other options include setting both with & height You wanted to resize your video (-vf scale'480:-1'), and at the same time you wanted dont to use a video codec for encoding such resized video (-vcodec copy). #- Scale can be used as is which will set the height to 560 but keep aspect ratio for width.
